FIELD

Embodiments of the present disclosure generally relate to the field of the device management, and more specifically, to a method and apparatus for managing a failure of a device.

BACKGROUND

A data center is a large place including various devices. The development of information technology has witnessed the exponential growth of the scale of the data center and an increasing number of devices (for example, servers, routers, switchers, storage devices, and the host machine bus adapter and so on) installed in the data center. Due to the growing number of the devices, device management in the data center becomes more and more complicated, and the resource consumption keeps increasing.

Traditionally, if a device in the data center fails, that is, a failure occurs in the device, the failure is generally analyzed separately and fixed according to the human experience. However, since the device failure is generally very complicated and varies from each other, failure fixing requires a large amount of human operations and professional technical knowledge. Meanwhile, some failures are recurrent, and separate analysis is conducted repetitively.

DETAILED DESCRIPTION OF EMBODIMENTS

Various example embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. The flow diagrams and block diagrams in the accompanying drawings illustrate system architecture, functions, and operations which are possibly implemented by the method and system according to various embodiments of the present disclosure. It should be understood that each block in the flow diagrams or block diagrams may represent a unit, a program segment, or a part of code; the unit, program segment, or part of code may include one or more executable instructions for implementing logical functions as prescribed in various embodiments. It should also be noted that in some alternative embodiments, the functions indicated in the blocks may also occur in a sequence different from what is indicated in the drawings. For example, two consecutively expressed blocks actually may be executed substantially in parallel, or they sometimes may be executed in a reversed order, dependent on the involved functions. Likewise, it should be noted that each block in the flow diagrams and/or block diagrams, and a combination of blocks in the flow diagrams and/or block diagrams, may be implemented using a specific hardware-based system that performs prescribed functions or operations, or may be implemented using a combination of specific hardware and computer instructions.

It should be understood that these example embodiments are only provided for enabling those skilled in the art to better understand and then further implement embodiments of the present disclosure, which are not intended to limit the scope of the present invention in any manner.

Embodiments of the present disclosure disclose a management approach for Device Object Modeling (DOM), and all the devices in a data center or a machine room are modeled in an object-oriented approach. Each device object includes some attributes, including but not limited to, a unique identifier (ID) of the device, a type of the device, a vendor of the device, a position of the device, and so on. Furthermore, each device object may include the operating status information of the device and the historical failure information of the device and so on.

FIG. 1 illustrates a flow diagram illustrating a method 100 for managing a failure of a device according to embodiments of the present disclosure. At 102, it is detected whether a failure occurs in a device. For example, all the devices or a part of the devices in the data center or the machine room may be detected manually or automatically to determine whether one or more failures occur. The failure(s) of the device(s) may be managed by a task management system in which one task may represent a device failure event. In an embodiment, the device is detected whether a failure occurs after a new task is generated in the task management system by an administrator. In another embodiment, the device can be detected periodically whether a failure occurs, and if the failure occurs, a new task is generated in the task management system.

In some embodiments, the operating status information (for example, the health status information representing the normal operating status of each device) of the device may be obtained, and it can be determined whether a failure occurs in the device based on the operating status information. The failure of the device may be a software failure or a hardware failure. The software failure may include, for example, a software error, a file damage, a data exchange error, a capacity error and an error of the operating system and so on. The hardware failure may include, for example, a power source failure, a component failure (for example, a hard disk failure and a mainboard failure), a connection failure and so on.

At 104, if the failure occurs in the device, a failure report for the failure is generated. For example, if the device fails, diagnostic analysis is performed for the failure, and a failure report is generated. The failure report may include information describing various types of the device failures, including but not limited to, a failure code, a log of the failure, an identifier of the device, a type of the device, a vendor of the device, and IP address of the device, a position of the device and so on.

In some embodiments, though a failure occurs in a certain device, the root cause of the failure may not be this certain device, but another device(s). As such, for a device failure, correlation analysis between the device and another device (for instance, Apriori algorithm analysis) may be performed in order to determine a root device causing the failure. For instance, if a server A has a network failure, the root cause of the network failure may be the failure of a switch B. Through the correlation analysis, an overall analysis between devices in the data center can be realized, thereby improving the efficiency of failure analysis.

At 106, the device object repository is queried with failure report, and the object device repository stores historical failure information associated with the device and the corresponding fix solution. In some embodiments, the failure code in the failure report may be used as a keyword for querying in the device object repository. Alternatively, a combined query may be performed with the type of the device, the vendor of the device and the failure code of the failure.

At 108, a corresponding fix solution is obtained from the device object repository based on a comparison between the failure report and the historical failure information. Through the query in the device object repository, the historical failure information that is most relevant to the failure can be retrieved, and the fix solution corresponding to the most relevant historical failure information may be obtained from the device object repository.

In some embodiments, a matching degree between the detected failure information in the failure report and each piece of the historical failure information may be determined, and the particular historical failure information that has the highest matching degree in the historical failure information are determined. Then, a fix solution corresponding to the particular historical failure information is obtained from the device object repository. In other words, the failure information is matched with each piece of historical failure information and the fix solution of the historical failure information with the highest matching degree is selected. In some cases, if the fix solution with the highest matching degree cannot fix the failure, the failure may be sent to the technical professional to be specially treated. In some embodiments, a matching degree threshold can be configured. For example, all the historical failure information with a matching degree that is higher than the matching degree threshold may be considered as the relevant failure information. In some embodiments, the matching degree includes a plurality of sub-matching degrees which include at least two of the following: a type matching degree, a vendor matching degree, a failure code matching degree and a failure log matching degree. For example, each sub-matching can be configured with different weights. For instance, if the relevancy of the failure code is most Importance, a weight of the failure code matching degree is configured as 0.4, and if the relevancy of the vendor is not so important comparatively, and a weight of the vendor matching degree is configured as 0.2.

In some embodiments, after obtaining the fix solution, the failure can be fixed with the fix solution. For example, the device is re-detected whether the failure still exists, and if no failure exists, the task is closed. That is to say, once the failure is fixed, the task corresponding to the failure is closed immediately, which facilitate the task management of all the devices in the data center thorough the task management system. In some embodiments, once the task is closed, the fix solution of the failure and the failure information are stored in the device object repository so that the content in the device object repository is added dynamically, and thus the following-up failure management of the device in the data center may be facilitated.

In some embodiments, the operating status information of all the devices may be obtained from the task management module for display so that the operating status information of all the devices may be seen directly from the dashboard. In some embodiments, all the historical failure information in the device object repository may be analyzed in order to predict failures of all the devices involved in the device object repository. For example, since some devices fail frequently, more attention may be paid to monitor the operating status information of the devices and some actions may be taken to prevent the occurrence of failure.

In some embodiments, the method for managing a failure of a device may be implemented manually or automatically with the following five components, for example, a Device Task/Ticket Management System (DTMS) 210, a Status Check Tool Set (SCTS) 220, a Diagnostic Analysis Module (DAM) 230, a Device Object Repository (DOR) 240 and a Device Health Dashboard (DHD) 250. However, embodiments of the present disclosure are not necessarily limited to the five components described above.

The DTMS 210 is a management system for managing all the hardware in the data center. The administrator of the data center can manage the device and the status of the device through the DTMS 210. If a device possibly has a failure, the DTMS 210 generates a new task and triggers the SCTS 220 to detect whether the failure occurs in the device. Furthermore, if the failure is fixed, the SCTS 220 runs again to check whether the failure still exists in the device, and closes the newly generated task automatically if no failure exists in the device.

The SCTS 220 is a validation set for various devices (for example, routers, switchers and so on), and the validation set may be maintained dynamically. For example, if the data center is equipped with a new device, the validation set for the new device is added to the SCTS 220. The SCTS 220 may run on various devices and report the healthy status of the device. If the SCTS 220 detects a failure, it reports the failure information to the DAM 230 for a further analysis.

The DAM 230 is an intelligent analysis module, which may analyze the failure information received by SCTS 220 and generate the failure report. The failure report can include an identifier of the device, a type of the device, a vendor of the device, a position of the device, a failure code of the failure, a failure log and so on. The DAM 230 can query DOR 240 with the information in the failure report and return the matched fix solution to the manager so as to fix the device failure.

The DOR 240 is a data warehouse including historical failure information of a plurality of hardware devices, and the historical failure information may be added automatically or manually so that the fix solution for fixing the failure can be reused. Each device in the data center can be considered as an object having various attributes, for example, a unique identifier of the device, a type of the device, a vendor of the device, a position of the device, status information of the device, historical failure information of the device and so on. The DOR 240 provides an external query to provide a recommended fix solution. In DOR 240, the historical failure information is stored in association with the fix solution corresponding to historical failure information. An example DOR 240 is shown in the following table:

TABLE 1
an example Device Object Repository
Device identifier              123456789
Device type                    HBA
Device vendor                  Cisco
Operating status of the device Good
Historical failure information Event XXX, YYY

The DHD 250 is a display module that can display information related to all the devices. The status information of all the devices may be obtained from the DHD 250. It should to be understood, although the DHD 250 is shown as a separate module, the DHD 250 may be integrated into the DTMS 210.

FIG. 2 illustrates a flow diagram of a method 200 for manually managing a failure of a device according to embodiments of the present disclosure. At 201, the DTMS 210 generates a task. At 202, the SCTS 220 detects whether a failure occurs in the device. At 203, if the failure occurs in the device, the DAM 230 performs the failure diagnostic analysis and generates a failure report at 204. At 205, DAM 230 queries the device object repository 240 with the failure report. Next, at 206, the device object repository 240 returns the recommended fix solution with which the administrator performs the fixing. After the failure has been fixed, at 207, the SCTS 220 verifies whether the fixing succeeds and re-detects whether the failure still exists in the device. If the failure has been fixed, the task is closed at 208, for example, the task is closed automatically. Alternatively, at 209, the DHD 250 may send a query request to the DTMS 210 to display the status information of all the devices in the data center.

FIG. 3 illustrates a flow diagram of a method 300 for automatically managing a failure of a device according to embodiments of the present disclosure. At 301, the status of the device is detected periodically on all the devices or a part of devices in the data center. At 302, it is determined whether a failure occurs in the device. If not, the status of the device continued to be detected periodically. Otherwise, the task management is performed in DTMS 210 at step 303, for example, a task of a failure event is generated. Next, at 304, the diagnostic analysis for the failure is performed. At 305, the device object repository 240 is queried based on the analyzed result (for example, failure report) in order to obtain the recommended fix solution. The failure is attempted to be fixed according to the recommended fix solution at 306. At 307, it is determined whether the failure has been fixed. If so, the task is closed automatically at 308. Otherwise, the failure is sent to the technical professional at 309.

At 310, after the failure has been fixed, the historical failure information in the device object repository can be analyzed. At 311, failures of all the devices in the device object repository are predicted. For instance, for the devices that frequently fail, more attention should be paid to the operating status information of the devices and some actions should be taken to prevent the occurrence of the failures. Then, at 312, the devices that fail frequently and have reached the service life threshold may be replaced automatically. Alternatively, if some devices fail frequently and are predicted to have new failure, the vendors of the devices may be notified for on-site check.
